1 Claim.

This invention relates to reels of relatively large size, such as those used for dyeing and other treatments of textile material. The conventional reel of this class comprises, with a shaft by which the power for rotating it is applied, spiders or other heads mounted on the shaft and staves extending generally lengthwise of and spaced from the shaft and mounted on the heads. The staves in the conventional reel have usually been of wood, but on account of the warping and incidental splitting which they undergo I have proposed, as in my Patent No. 2,073,063, to construct them, as well as the shaft and heads, of metal. all rigidly connected to each other, as by welding, wherefore, due to considerable changes in temperature which the reel undergoes, as where a heated dye bath is used, it is found that expansion and contraction in time causes some part of the reel to become distorted and actually rupture at some point to occur. Expansion and contraction primarily affect the staves, that is to say, with the effect of changing their longitudinal dimension, and it is this condition of which account has to be taken.

The object of this invention is to provide a reel constructed to permit relative displacement of parts thereof and including a shaft, heads and staves all of which may be of conventional form except for portions of at least one head and of the staves whereby the latter are confined against substantial displacement in any direction crosswise of the shaft but relative displacement as between such head and the staves lengthwise of the shaft may freely occur. To these ends there are the shaft and at least two heads penetrated by and fast to the shaft and staves extending lengthwise of the shaft and spaced therefrom and from each other and each fast to one head and traversing the other head; and each stave and the head traversed thereby have, wholly exterior But in such case the several parts were of the periphery of the latter, intercoupled lamishowing a fragment of the shaft in elevation; and

Fig. 4 shows a fragment of the reel in left-hand elevation, broken away between the portions shown. 7

The shaft is designated I. 2 is the heads, each formed of sheet metal and having the shape of a lozenge, here truncated where the angles would otherwise exist; the margin of the blank from which each head is formed is bent off perpendicularly, thus to provide a continuous flange 2a. 3 designates the set of staves, they being here counterparts of each other and formed as elongated hollow cross-sectionally hexagonal boxes of sheet metal, their interiors being sealed off so as to exclude admission of dye or other liquid therefrom.

There are in this example three heads, but the number is not material so long as there is at least a plurality. As positioned on the shaft they will have their common (as long) diameters in the same radial plane. The staves extend here actually parallel with the shaft, there being four respectively opposed to the truncated sides of the heads.

Each head is penetrated by the shaft and is made fast thereto, as by welding. For inter coupling the staves and heads the construction is as follows:

Each head has fast to its periphery, to wit, the outer surface of its flange, as by rivets 6, pairs of clips 1 having the adjacent terminals Ia thereof diverted from such surface and projecting toward each other. Each stave has fast thereto, as by welding, plates 3a each extending transversely thereof and having its terminals projecting beyond margins of the stave. With respect to any stave the plates thereof, in the assembled state of the stave and the heads, are between the clips of the respective pairs 1, with the terminals of the latter overlapping those of the plates. Such plates and clips therefore provide the heads and each stave with the mentioned portions wholly exterior of the heads and intercoupling such heads and stave whereby the stave is confined against substantial displacement in any direction crosswise of the shaft, although, except as will appear, the stave, while fast against displacement lengthwise of the shaft relatively to one, is freeto undergo such displacement relatively to the other heads. The mentioned exception is with respectto each stave and one of the heads, here the middle one, to which in this example all the staves are rigidly secured by having threaded studs 4 penetrating the flange of such head and equipped with nuts 5. With respect to each of the other heads, the mentioned intercoupling permitting displacement of the stave relatively thereto lengthwise of the stave here results from the laminated relation of the projecting margins of the plates 3a, the parts of the clips 1 which overreach such margins and the flange 2a (of such head) underlying the plates, the thus laminated layer portions having their adjoining faces parallel with the shaft.

It is not material that all the staves should be fast to the same head.

Having thus fully described my invention, what I claim is:
